We have designed this tray specifically for wide sofa armrests, suitable for armrests ranging from 1 to 9.7 inches, offering better stability. The top box of the sofa armrest table can be used independently as a storage box or tray, or it can be combined with the support legs for use. The sofa armrest table comes with a storage box, which can hold various small items not exceeding 1 inch in thickness, such as remote controls, chargers, nail clippers, etc. The lid of the storage box can rotate 360°, serving not only as a tray for placing fruits, cups, books, and other items, but also for easy access to the items inside. The lid is equipped with a 360°rotatable phone holder, making it convenient to place devices like phones, Kindles, tablets, etc. You can adjust the distance by rotating the lid, which reduces neck strain and provides a more comfortable user experience. To ensure your new tray fits like a glove, we kindly suggest you measure your sofa arm's width (flat surface area where the tray rests).
